A reference point identification of point clouds, the image data are produced from geographical

摘要

A computer system for identifying marked reference points in a geographic area, wherein the computer system comprising:a processor or more processors;one or more computer readable media, the computer readable instructions storing, which, when it from the one or more processors, that the or the processors processes performing;a structure - from - movement - module, is implemented by one or more processors, wherein the structure - from - movement - module is configured such that at least in part on the basis of the geographic image data of a point cloud is generated, wherein the point cloud comprises a plurality of data points and each of the plurality of data points a tracked feature in the geographical image data is associated with;a filter module, is implemented by one or more processors, wherein the filter module is configured such that a subset of the data points in the point cloud is identified, wherein each data point in the subset of data points at a distance of at least one threshold value of one or more camera perspectives is located, which are associated with the geographic image data; andan adjustment module, is implemented by one or more processors, wherein the calibration module is configured to one or more data points in the subset of data points with a reference point can be brought into conformity.
